Dark Mode to avoid eye strain!
I find it uncomfortable to stare at white menus while in edit mode. The only way for me to darken these menus at the moment is to edit the objects color within menu. A Dark Mode would make eye strain in edit mode less of an issue.
Yes the brightness overall isn't the issue, but the tweak menus are white and the only way to darken them is to recolor the object. If they were grey or darker it would be a lot easier to look at.
Oh for VR! There are VR settings for brightness.
You could adjust your TV's settings?
